目的:观察使用7号头皮针为2周岁以内婴幼儿行骨髓穿刺术及取骨髓涂片效果。方法:86例年龄为6~24个月需行骨髓穿刺术的婴幼儿随机分为观察组和对照组。观察组使用7号头皮针在胫骨粗隆前下方行骨髓穿刺术,对照组使用传统骨髓穿刺针在胫骨粗隆前下方行骨髓穿刺术。观察两组骨髓标本稀释情况,穿刺针眼渗血情况、穿刺过程情况。结果:观察组骨髓标本稀释2例,对照组骨髓标本稀释18例。两组差异有统计学意义(P<0.01);两组均无血肿及穿刺处渗血情况。结论:使用7号头皮针为2周岁以内的婴幼儿行骨髓穿刺术较传统骨髓穿刺针有明显的优势;7号头皮针可取代传统骨髓穿刺针为2周岁以内婴幼儿行骨髓穿刺术。
Objective: To observe the use of 7 scalp acupuncture for bone marrow puncture and bone marrow smear in infants under 2 years of age. Methods: Totally 86 infants and young children who underwent bone marrow aspiration for 6-24 months were randomly divided into observation group and control group. In the observation group, the 7th scalp acupuncture was used to perform the bone marrow puncturing before the tibial tuberosity, while the control group was to undergo the bone marrow puncturing before the tibial tuberosity using the traditional bone marrow puncture needle. Two groups of bone marrow specimens were observed for dilution, puncture needle eye bleeding, puncture process. Results: The bone marrow specimens of the observation group were diluted in 2 cases and the bone marrow samples of the control group were diluted in 18 cases. The difference between the two groups was statistically significant (P <0.01); no hematoma and puncture site bleeding in both groups. Conclusion: The use of 7 scalp acupuncture for bone marrow biopsy in infants younger than 2 years has obvious advantages over traditional bone marrow puncture needle. The 7 scalp acupuncture needle can replace the traditional bone marrow puncture needle for bone marrow puncture in infants under 2 years of age.
